Research ArticleOpen accessIn the keywordsThe Effect of Reaction Temperature on Retaining Oxirane Oxygen Contents in the Synthesis of Epoxidized DiethanolamidesC. S. Lee, T. L. Ooi, C. H. ChuahEpoxidized diethanolamides were synthesized by reacting diethanolamine (DEA) with mixture of Epoxidized Palm Olein (EPOo ,40% w/w) and Refined Bleached Deodorized Palm Kernel Olein (RBDPKOo , 60% w/w) at 1:3 molar at 80°C for 5 h and continued at 110°C for another 4 h of reaction time. Synthesized diethanolamides with high content of epoxides were reacted with isocyanate in the … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,372 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Bisphenol A Polyether Polyols on the Synthesis of Hydrophilic Epoxy ResinsJinhua Yi, Xin YuanThe article uses three types of Bisphenol A polyether polyols BEO, BPO-6 and BPO-10 as raw materials, reacts with epichlorohydrin under the action of a catalyst and synthesizes a hydrophilic epoxy resin. The molecular structure of the product is analyzed by infrared spectroscopy and the results show that the synthesis of the hydrophilic epoxy resin BEOGE conforms to the results … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 3 · 15 Jul 2021 · 7,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATING EFFECTS OF AMINE BASED MODIFIER ON RECYCLED ASPHALT SHINGLES BLENDINGGovinda Sedhay, Elham H. Fini, Taher Abu-LebdehA laboratory study was conducted to investigate the effects of Amine based modifier on rheological characteristics of particle filled viscous medium such as asphalt binder in presence of Recycled Asphalt Shingles (RAS). In this study, virgin asphalt binder (PG 64-22), three different percentages (20, 30 and 40%) of tear-off shingles and modifiers; Rediset, Evotherm and Bio-binder were used. The tear-off … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 26 Mar 2014 · 8,723 accessesView PDFCite
Research ArticleOpen accessIn the abstract2-Nonenal-Ovulatory Specific Volatiles in Human Saliva throughout Menstrual Cycle by Gas Chromatography and Mass Spectrometry AnalysisS. Alagendran, G. Archunan, K. Rameshkumar et al.Problem statement: The present investigation carry out a pilot study of a novel method to identify the salivary volatiles in different phases of menstrual cycle for the assessment of ovulation detection using gas chromatography and mass spectrophotometer. Approach: The profiles from follicular phase (6-12 days); ovulatory phase (13-14 days) and luteal phase (15-26 days) of menstrual cycle samples were compared … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 8,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Investigation of 1H NMR Spectra of 2,3-Dihydro-4-Pyridinones Derived from BisdemethoxycurcuminWisam A. Radhi, Bahjat A. SaeedProblem statement: The studied dihydropyridones were synthesized via microwave assisted reaction of bisdemethoxycurcumin and amines or amine acetates which is new approach in the synthesis of this important class of compounds and the deep study of their NMR spectra seems reasonable. Approach: 1H NMR spectra of dihydropyridones derived from curcumin were discussed and their structures were elucidated accordingly. Results: The … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,186 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThermal Control of a Greenhouse by Variation in Ventilation Rate using a Fuzzy Parallel Distributed Compensation Controller with an RST Regulator in Each RuleElyes Feki, Amine Chouchaine, Abdelkader MamiProblem statement: The greenhouse has uncontrollable inputs that affect its climate, which arises the difficulty to regulate its inside temperature. The solution can be found using a multi-system approach like the Takagi-Sugeno System from which a design of a Parallel Distributed Compensation (PDC) controller is performed. However, a stability problem arises and was negotiatesd in general based on a Lyapunov … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 27 Apr 2012 · 7,098 accessesView PDFCite
